1. The size of a quantity is called (a. vector b. scalar c. ratio d. magnitude). 2. A quantity of 12 mi/sec to the north is a measure of (a. velocity b. acceleration c. speed d. directional distance in the metric system). 3. A quantity of 55 km/hr describes a motion known as (a. vector b. acceleration c. speed d. metric distance). 4. A quantity of 10 m/sec is a measure of (a. metric area b. acceleration c. speed d. velocity).
